First Class How-To video. Straight and to the point, no fluff, no
useless commentary. Real teaching. I changed the gear lube in my stern drive after
watching this and it was all accurate information that made the change
so much easier than I imagined. Thanks again! Keep them coming!

Great video. One question: Do I have to put grease on the screw before I put them back in? One guy told me to put light bulb grease on the screws o ring to prevent water from getting into the sterndrive

Great video. New boat owner and just did this on it. Simple!

[deepee]

Another excellent video!! I'm so pleased you decided to do this. Much better than other videos I've seen on the same procedure. Well planned and executed.

Can i just fill through the vent hole with the bottom plug in until it comes out the top?

[GenYShyGuy]

Only thing I would change, is always undo the vent plug before the drain.
What if you drain the oil and the vent screw is seized in? You can’t get it out, you can’t fill the oil. Headache can be avoided by undoing the vent screw first.

Soooo.. I see a bunch of these videos being done from land. What's the best way to do it while my boat is on a boat lift over water ....

[Capucee]

Where do i find the fill screw ? And what is it called ?

Can i add regular 75W90 gear oil on the stern drive instead of marine gear oil

[elitebowman]

how much oil does the stern drive Mercruiser take? I have a friends motor lower unit he asked me to put oil in. He already drained the oil. I bought CRC Marine Hypoid 90 Lower unit oil and put 2 tubes in plus had little more, so like 20 plus ounces and wasn't enough. Any help would be appreciated so I can have an idea how much more oil I need. Thanks

Any way to check the oil level in the 1st gen ?

[Jonhawblitz]

Can I top off the through the dipstick hole if need be?

[RadioClik]

Do you know where can l find the hours on a see ray185 1997 ? Thanks

[jpraba]

I might have missed the gear oil reservoir needs to be topped off as well.

[ryancorse]

I was curious about the gear lube container up under my engine hatch. My mercy has a container. Can i follow this video for my boat or do i need to do something different? Please and thank you

Incomplete procedure. Did not address the drive lub monitor, drainage and refilling which is part of the mercruiser maintenance procedure. Also did not address oil spec.
